In architecture, the term precision, in the sense of “respect for order and exactness”, explains everything. No error is allowed!
Cherry red heated, horse shoe being sized and shaped on the miniature anvil that he carries in his work truck.
Seen on a overcast muggy day moored up on the River Mersey at Birkenhead with Liverpool's world famous Liver Building in the background. The bright colours of the newly repainted ship jump out at you from the subdued surroundings.
An F-22 Raptor stands silhouetted on the tarmac at Cocoa Beach Airshow 2025, its angular stealth design highlighted by the warm glow of sunrise or sunset. The aircraft’s sleek profile and commanding presence evoke cutting-edge aviation and quiet power. Captured in dramatic light, this moment blends military precision with atmospheric beauty, showcasing one of the world’s most advanced fighter jets.

The U.S. Navy Flight Demonstration, the Blue Angels performed at the Defenders of Freedom Offutt Air Show this past weekend. The Blue Angels are scheduled to perform 68 demonstrations at 34 locations across the U.S. in 2014.
This was a backyard photo. What a thrill to see them right over your house. This was taken at 110mm which gives you an idea of just how close they were. The noise was unbelievable.
I wasn't sure whet I was going to use for this challenge and then I thought about these which I used recently.
Belonged to my Father although I don't know what he used them for. They are worn on the head and the magnifier is hinged to lift up out of the way when not using. Provides hands free magnification and so it is very useful. This is in its original box, the bottom of which is velvet lined for protection. I used them recently when looking for that dreaded broken needle inside my machine. Ideal for close intricate work potentially jewellery work
The last one before I leave for a week.
I was gonna use this for the old WWII weapons contest (that SPW one). But i didn't finish on time, so i re-built it in my style.
Have fun!

Precision strike in the canopy
A Brown-hooded Kingfisher (Halcyon albiventris) grips a freshly caught Striped Skink—a moment of instinct, agility, and survival. These kingfishers aren’t just about water; they’re woodland hunters, often found far from rivers, ambushing insects, small reptiles, and even amphibians.

Built in 1930's as an experimental bombing range. It involved the use of state-of-the-art equipment for tracking the flight of bombs in order to improve their aerodynamics and to produce tables to refine the precision of bomb aiming.
The church hosts also a marking in the form of a meridian line inlaid in the paving of the left aisle in 1655; it was calculated and designed by the astronomer Giovanni Domenico Cassini, who was teaching astronomy at the University. A meridian line does not indicate the time: instead, with its length of 66.8 metres (219 ft) it is one of the largest astronomical instruments in the world, allowing measurements that were for the time uniquely precise. The sun light, entering through a 27.07 mm (1.066 in) hole placed at a 27.07 m (88.8 ft) height in the church wall, projects an elliptical image of the sun, which at local noon falls exactly on the meridian line and every day is different as to position and size. The position of the projected image along the line allows to determine accurately the daily altitude of the sun at noon, from which Cassini was able to calculate with unprecedented precision astronomical parameters such as the obliquity of the ecliptic, the duration of the tropical year and the timing of equinoxes and solstices. On the other hand, the size of the projected sun's image, and in particular its rate of variation during the year, allowed Cassini the first experimental verification of Kepler's laws of planetary motion.
Cassini and Domenico Guglielmini published an illustrated account of how the meridian line was accomplished in 1695.

La iglesia también alberga una marca en forma de línea meridiana incrustada en el pavimento de la nave izquierda en 1655; fue calculada y diseñada por el astrónomo Giovanni Domenico Cassini, que enseñaba astronomía en la Universidad. Una línea meridiana no indica la hora: en cambio, con su longitud de 66,8 metros (219 pies), es uno de los instrumentos astronómicos más grandes del mundo, lo que permite mediciones que para la época eran excepcionalmente precisas. La luz del sol, que entra a través de un orificio de 27,07 mm (1,066 pulgadas) colocado a 27,07 m (88,8 pies) de altura en el muro de la iglesia, proyecta una imagen elíptica del sol, que al mediodía local cae exactamente sobre la línea meridiana y cada día es diferente en cuanto a posición y tamaño. La posición de la imagen proyectada a lo largo de la línea permite determinar con precisión la altitud diaria del sol al mediodía, a partir de la cual Cassini pudo calcular con una precisión sin precedentes parámetros astronómicos como la oblicuidad de la eclíptica, la duración del año trópico y la sincronización de los equinoccios y solsticios. Por otra parte, el tamaño de la imagen proyectada del sol, y en particular su tasa de variación a lo largo del año, permitieron a Cassini la primera verificación experimental de las leyes de Kepler sobre el movimiento planetario.
Cassini y Domenico Guglielmini publicaron un relato ilustrado de cómo se logró la línea del meridiano en 1695.
Hay objetos que tienen que ser fabricados con mucha precisión para que sean realmente útiles y los sacapuntas, no iban a ser menos.
